For weeks, a benevolent bar-crawling superhero has been lighting up his tabs with astoundingly generous tips, totaling over $50,000. Now we know how he does it: he's Jack Selby, a former PayPal VP with more money than the real son of God.

The PayPal Mafia, that group of legendary payment alumni who cashed out astronomically, isn't usually known for populist ploys—they're usually building spacecraft or planning sinister floating libertarian utopias. Not Jack Selby! Since leaving PayPal, Selby has dabbled in both film production and venture capital—where he famously got in a screaming match with Peter Thiel. Now, his secret Instagram account has "gone viral," as the teens say, since followers started to spread the word of his mammoth gratuities. And people absolutely love him.

For example, this insane $10,000 tip on an already insane $3,000 liquor tab (including a $102 gimlet—Jesus Christ indeed):

Or a $1,000 tip after some tacos:

Selby hasn't revealed himself anywhere since his online fame, though his Facebook friends seem to be in on the secret benevolence:

It doesn't seem like the @TipsForJesus account is tied to any new project, or any apparent religious fervor—a tipster told me all the Jesus talk is a joke, even if his Instagram fans are in a rapture of gratitude. True Jesus freak or not, Selby is laudable for being one of the few people of his kind that still bothers interacting with other humans in the service industry, without the use of some sort of mediating app.
